Wi-Fi makes trees sick, according to Dutch study
A study by Wageningen University in the Netherlands claims that radiation from Wi-Fi networks is causing serious harm to trees.

Wi-Fi sickness: About 70% of trees in urban areas are showing symptoms, compared with 10% 5 years ago.

Side effects include significant variations in growth, as well as bleeding and fissures in the bark.

The harmful radiation is believed to effect all deciduous trees in the Western world, a very worrying discovery given that we are reliant on trees for our existence.

Twenty ash trees were exposed to varying levels of radiation, with the trees situated closest to Wi-Fi stations being the most damaged.

A ‘lead-like shine’ appeared on the leaves that was caused by the dying of the upper and lower epidermis, according to researchers. This would eventually result in the death of part of the leaves.

In addition to the electromagnetic fields produced by mobile phones and LAN networks it is thought that ultra-fine particles emitted by cars may also be to blame.

Further research has been commissioned to examine the severity of the damage to trees.
